Specification of Letters Patent.

Patented May 1, 1906 Application tiled July 28,1903. Serial No. 167.282.

To a whom it may concern:

Be it known that I, DANIEL L. EUSTiCE, a citizen of the United States, residin in the city of Galena, in the county of Jo aviess and State of Illinois, have invented certain new and useful Improvements in Machines for the Manufacture of Bands; and I do hereby declare the following to be a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

In the manufacture of devices for the individual transportation of cans, buckets, pails, and the like there is sometimes formed a band adapted to be clasped around the can and provided with ears in which the bail or handle is hooked. So great difiiculty has been experienced in the manufacture of these bands, especially where the ears are formed with round shoulders of sufiicient height to prevent the hail from droppin out of the ears when the hold on the bail is re eased, that it is the custom to make them separatel and then unite them to the can. This mo e of con struction, however, is expensive and not as strong or useful as when made integral. To overcome these difliulties and to provide means whereby these bands with integral ears and a clasping device may be cut out from a sheet and finished completely at one operation of the machine, is the leading object of this invention.

The manner of accomplishment will be set out in detail in the followin specification when taken in connection wit the drawings accompanying the same and forming a part hereof.

Figure 1 is a perspective view of the band formed by the machine. Fi 2 is a perspective view of the machine gram the front Fig.3 is a perspective view of the upper stamping plate or die including the cutter-bar. Fi 4 is a perspective view of the lower die. l ig. 5 is a longitudinal section through the line X X of Fig. 4. Fig. 6 is a erspective view of the stripper removed.

Fig. 9 is an enlar ed perspective view of a portion of Fig. 7. i ig. 10 is a vertical section of one of the d1es.- Fig. 11 shows a section of the female dies for forming the ears, showing a punch for punching the holes in the ears. Fig. 12 is a side view of Fig. '2.

Like characters of reference denote correspondin parts in each of the figures.

In or er that there may be a better understanding of the requisites of a machine for manufacturing this band, there is set out in Fig. 1 a perspective view of the band complete in which A represents the band. This is formed of a single piece in three divisions or parts B, D, and E. At the junctionof the divisions B and D and D and E are formed integral therewith circular ears G, which are provided with shoulders (2, formed nearly at right angles to the plane of the division and each provided with a hole H throu h the to These ears are also enlar ed at t e base The end of the division is formed into a tongue K, adapted to engage a rectan ular opening P, out near the end of division by which the band is fastened around the body of the can with which it is to be used.

their shoulders and widened bases, are formed into ral with the balance of the band the ban when completed will be considerably shorter and narrower at the base of the ears,

provide means for furnishing this extra n1aterial and still have the ears integral with the band constitute the leading features of the machine.

Referring to the drawings, 2 designates the base of the machine, having side plates T and 4, preferably cast integral with the base, with an opening 2 in each side late and consti tuting the frame of the mac line. In the top of the lates T and 4 there are provided two jouma -bcarings 5 and 6, in which a crankshaft 8 is adapted to be rotated by a drive- ;whcel 10, belted to the power by the belt 11. Between the side plates T and 4 is a slide 12 adapted to slide up and down in grooves (not shown) in the side plates. This slide is operated by a connecting-rod 14, pivoted to the shaft 8. To the lower end of the slide 12 is attached a block15, into which is secured a cutter bar 18, provided with two cutting edges. This cutter-bar is formed of an integral piece in three divisions 19, 20, and 21 to corres 0nd to the divisions B, D, and E of the ban The divisions 19 and 20 are curved for the purpose recently to a pear. At the junction of the ivisions 19 an 20 is set a female die 25, (shown in Fig. 11,) in which is located a punch for punching the It will be observed that as the ears, with hole H in the to' of the shoulder, and at the {unction of the ivisions 20 and 2]. is a simiar die 25, also provided with a punch. At the ri lit-hand end of the cutting-bar 18 is a die S For cutting the hole or rectangular 0 ening P in the band, and the other end 0 the cutter 18 at R is formed so as to cut out the tongue K.

In the base of the frame is a recess 30, and u on the base over the recess is secured a b ock 35, rovided along its top with a block 36, with t is art 17 slightly raised, in which is a rectangu ar opening 40, corres onding-in shape with the cutter-bar 18 and aving the curved divisions 41 and 42. Within the opening 40 at the junction of the three divisions are set two dies 45. (Shown in Fi s1 5 and 10.) These dies each consist of a tu 46, which is screwed into a block 48, said block 48 terminating in a tube 50, thus providing a continuous hole through the tube 46 and the tube 50. Loosel around the end of the tube 50 is a tubular plhte 54, provided with a shoulder 53, which fits the end of the block 48. Around the tube 46 is loosely set a circular plate 55, provided with several pins 56, adapted to be moved in holes 57 in the block 48 and engage the shoulders of the late 54 for the purpose presently to appear. ear the bottom of the tube 46 is a head 58, and around the tube 46, between the head and the plate 55, is a coil-spring 60, ada ted to force 11 the plate 55 and by the ro s 56 force the p ate 54 to the end of the tube 50.

For the urpose of removing the band from the dies a ter it has been cut off there is rovided a stripper 61, (shown in Fig. 6,) w 'ch consists of a plate 62, to which are secured several rods 63, 64, and 65. To the ends of each of the rods are attached lates 66, 67, and 68 of nearly the width of t e opening 40 in the block 36 of block 35. This stripper is attached to a shaft 71, rovided with a collar 73, which is provi ed with a lug 77, through which is a hole 81. For the purpose of operatin the stripper 61 there is provided a rod 70, bifurcated at its up or end, in which is pivoted a bar 69, attache to the slide 12. This rod 70 extends down into a sleeve 75, around which is a band 72, having an 0 ening 95 corresponding in shape to the catc 74. Tothe lower end of the sleeve is pivoted a clutch or shackle 76, provided with a slot 78 at its opposite end which on ages a pin 79 in the recess 30 of the base o the sleeve 75 is pivoted a hook 80, adapted to engage the notch or catch 74. In the top of the hook 80 is pivoted a roller 82, and to the rear of the hook is secured a spring 84, adapted to engage the end of the shackle 76 and hold the k 80 in engagement with the catch 74. The shackle 76 1S loosely attached to the shaft 71 by a thumb-bolt 88, passin through the hole 81 in the lug 77. (See igs. 6, 7, and 8.) i

The manner of operating my device is substantially as follows: Starting with the l1Hlchine in the position shown in Fig. 2 with the dies and cutter-bars separated, the sheet out of which the band is to be cut is inserted between the cutters 18 and block 36 and power is ap lied to the pulley 10, which 0 )erates the s iaft 8 and connecting-rod 14 and forces down the slide 12, and with it the block 15, till the sheet is gras ed between the tubes 50 and the edges of tie dies 25 at the places where the ears are subsequently formed and the curved edge 19 of the cutter 18 has come to the slot 40 at the curve 42 in the block 36, when it will commence to cut the divisions B of the band, then as it still slightly further advances it will commence to out part of the division D at the curve 41 and at,the same time commence to cut around the base of the ears. The reason for cutting these parts first is to provide sufficient material for forming the ears and the rectangular opening P in the band. A further downward movement of the block 15 will completely out out the strip from the sheet, except a minute space on one side of each end of the blank, just suilicient being left to hold the blank steady. At this junction the ears have just commenced to be formed by the rim of the dies 25 pressing down upon the top of the tubes 50. This blank now will be considerably longer than the completed band and will also be wider at the base of the ears. When the cutter-bar has advanced a trifle farther, the blank is entirely severed from the sheet, and shortly thereafter the ears, with their bases and holes punched in the top, will be formed and the rectangular opening cut out and the band finished. It will be seen that when the blank is placed between the dies to be cut it is straight; but the instant that the cutting commences the block 15 will bend the blank to conform with the upper surface of the block 36 and the end surfaces of the cutterbar 18 of the block 15. Then as the cutting commences the parts of the band out out by the division 19 will pass down into the slot 40, curved in practically the shape of the cutter-bar 18, and when the ears are formed the extra material in the blank will be taken up and the completed band will lie in a straight line in the slot, while the sheet of metal from which the band is about to be severed conforms to the curved surface of the block 36. Hence the com leted band is shorter than the sheet from which it is cut. The curved surface of 36 is so shaped that the exact amount of metal required to form the cars is the difference between the length of the circumference of the curve and the length of a straight line between the same two points It Wlll also be seen that the length of the blank from which the band is formed is longer than the completed band, and the exact diference between their lengths is taken up into the cars, and hence there ivill be no stretching" of the bend or buckling of the blank and that the blank is not entirely severed until just an instant before the ears are completely finished. The continued rotation of the shaft 8 will commence to raise the cutterbar 18 out of the o ening 40 in the block 36. This will draw up t e arm 70, and with it the shackle 76, which will raise the stripper 61 pushing up the plates 66, 67, end 68 and orcing the band out of the slot 49. At the same tune the s ring will come mto action and force the p ates 55 up against the block 48, and the pins 56 will engage the base of the late 54 and push the ears of the band off cm the end of the tube 50. As the block 15 rises much higher than the stripper when the stripper has reached the position to throw off the completed band, roller 82in the end of the hook 80 will have come in contact with the side of the recess 30 in the base, which will release the hook 80 from the catch 74 and allon the rod to be raised in the sleeve 75 still farther without raising the stri per. It will be seen that as the division B o the band is cut oil' from the sheet and then divisions D and E before the cars are fully formed there will be provided sufficient metal in the band to form the ears and cut out the slot P without stretching of the band and also that the tubes 50 will only force the extra. metal into the die 25 and form the ears without on longitudinal strain whatever upon the ban It will further be observed that the cutters are arranged so as to cutout different parts of the blank sequentially, and the dies are arranged to take up into the ears all of the extra material in the blank nearly as fast as the cutters out it out and when the blank is completely severed from the sheet the ears are nearly completed and it is onl necessary for the dies to be advanced a trade to complete the band and appropriate into the cars all of the extra material in the blank.
